You should have just tried it. I signed up and got the following response:

Thank you fellow luminary! You have taken an essential step in reducing greenhouse gases in America. Now tell you friends about this project, and continue to take the little steps to help with global warming.

Your bulb will be sent to you in the mail in the next few months. We thank you for your patience, as this is a big undertaking to send out one million bulbs across America.
